A suitable opening 14- with a diameter readily to receive the boss 11preferably is formed in the floor 9. A central opening 16 is provided inthe boss and receives an expansion bolt 17, the head 19 01 which isdisposed above the horizontal .vall 10. This bolt may be provided. witha tapered nut portion 20 and with the expansible member 21 havingductile fingers 22. Tightening of the bolt results in the drawing of thetapered nut portion 20 toward the head 19, thus causing the expansion ofthe ductile portions'22 of the member 21 into firm engagement with thesides of the opening 14, and ensuring the firm anch ring of the assemblyto the floor. After the bolt has thus been tightened it preferably isslightly loos ened, as shown in Fig. 1, so that the member 4 may berotated to permit its being threaded into engagement with the lower endof upright 1.

In the installation of connections or" this character, it is evidentthat the openings 14 are first provided at properly spaced intervals inthe floor and that the expansion bolts 17 are assembled in looseengagement with the members l and the expansible portion at the lowerend of the bolt and the boss 11 of the member l is disposed in one ofthe suitable cylindrical recesses Ll in the floor. A wrench may then beextended through the opening provided by the annular upper edge ofmember i and engaged with the head 19 or" bo t 17, the latter beingrotated to tighten the tapered nut and to force the ductile elements 22into firm engagement with the floor material. Bolt 17 is then turned inthe opposite direction sufliciently to loosen the engagement of its headwi h the horizontal wall 10 of the base member so that the latter may beturned. After all of the connections have been located in this manner,the stand, rack, or the like may be brought into position, the uprightsl of the same being dropped through the openings in the upper ends ofthe frusto conical base members and brought into engagement with theannular flanges 6. vThereupon the base members are rotated to ensure thefirm interengagement of the base members and the uprights and the properadjustment in height or" the rack or the like. 7

It is thus evident that a connection has been provided permitting thefirm anchoring of uprights forming portions of a stand, rack, or thelike, so that longitudinal movement of the same in relation to the flooris prevented, the weight of. the assembly cooperating with thisanchorage to prevent even a slight vertical movement. Furthermore, aconnection of this characterprovides a smooth outer surface and is freefrom irregularities or corners that are adapted to collect dirt.Accordingly a particularly satisfactory and sanitary connection isprovided for locations where such a feature is essential as, forexample, in hospitals, clinics, food-producing or handlingestablishments, and the like.

I cl im:

1. A connection between the lower end of an upright and a floor,comprising a base member receiving and substantially enclosing the lowerend of the upright, the upper portion of the base member having a partof small diameter in juxtaposition to the upright and having a lowerportion of larger diameter inlengagement with the surface of the floor,a central depending projection of the base member being received in anopening in the floor and held against longitudinal movement in relationto the same, said base member being hollow and having an internallythreaded annular flange intermediate its upper and lower portions, theupright being threaded into engagement with said flange.

2. A connection between the lower end of upright and a floor, comprisinga base member receiving and substantially enclosing the lower end of theupright, the upper portion of the base member having an opening throughwhich the upright extends and having an a lower portion of largerdiameter resting upon the floor, an intermediate depending projection ofthe base member being received in an opening in the floor, andexpansible means disposed in the depena 'ng portion of the base memberthat is received in the Opening in the floor and expanded into firmengagement with a portion of this opening that is spaced below thesurface ofthe floor.

8. A connection between the lower end of an upright and a floor,comprising a base member receiving and substantially enclosing the lowerend of the upright, the upper portion'ot' the base member having anopening through which the upright extends and having a lower portion oflarger diameter resting in engagement with the surface of the floor, anintermediate depending projection of the base member being received inan'opening in the floor and held against longitudinal movement inrelation to the same, said base member being hollow and having aninternally threaded annular flange intermediate its upper and lowerportions, the upright being threaded into engagement with said flange,expansible means disposed in the dependnig portion of the base memberthat is received in the opening in the floor and expandcd'into firmengagement with a portion of this opening spaced below the surface ofthe floor.

l. A connection to secure an upright to a floor, comprising a basemember having an upper portion of restricted diameter adapted to receivethe upright with a sliding fit and having a lower portion of largerdiameter adapted to rest upon the floor, and a depending centralextension of this lower portion providing an opening to extend 1nto thefloor, a central opening being provided in said depending portion topermit insertion of an expansion bolt through the base member.

5. A connection to secure an upright to a floor, comprising a basemember having an upper portion of restricted diameter adapted to receivethe upright with a sliding fit and having a lower portion of largerdiameter adapted to rest upon the floor, and a depending centralextension of this lower portion providing an opening to extend into thefloor, a central opening being provided in said depending portion topermit insertion of an expansion bolt through the base member, aninwardly directed flange intermediate the upper and lower portions ofthe base member provided with internal threads adapted to be engagedwith external threads upon the upright. 7

6. In combination, a substantially cylindrical upright having a threadedlower end, a hollow frusto conical base memberhaving an annular upperedge in juxtaposition to the cylindrical surface of the upright andhaving an annular internal flange in threaded engagement with thethreaded end of the upright below said-annular upper edge, a centraldepending extension, of the base member received in an opening in thefloor, a central opening in said extension and an expansion boltextending through said opening and having its expansible portion inengagement with the opening in the floor below said depending extension.
